Drilling glass and tile

This carbide-tipped drill bit creates round holes in glass, ceramic and marble tile without chipping or breaking the material. Tungsten carbide spear points deliver clean results. The bit is designed for rotation only and must not be used with percussion drilling. Slow drilling speeds are recommended for best performance.

Suited for tile installers, not for percussion users

Installers who need precise holes in fragile surfaces will find this bit reliable for glass and tile work. It is not suitable for anyone requiring hammer or percussion action. Builders who need a percussion-rated bit should look at a different tool. The single-purpose design limits it to rotational drilling tasks.

3/8 inch diameter decides fit

The 3/8 inch bore size determines whether the bit matches the anchor, fastener or fixture you are installing. Verify the required hole diameter before purchase. The overall length of 3-3/4 inches sets the maximum drilling depth. No other specification overrides this dimensional constraint.

Questions about this item

How do I install the 3/8 inch glass tile drill bit in my drill without damaging the carbide tip?

Insert the shank fully into the chuck, tighten securely, select rotation-only mode, and run at slow speed to prevent tip fracture.

When will the carbide tip on this bit need replacement during tile work?

Replace when the tip dulls enough to chip tile edges or when drilling speed drops noticeably in ceramic or marble.

What limit appears first when drilling multiple holes in glass with this bit?

Heat buildup at the carbide tip reduces cutting efficiency and risks cracking the glass if speed is not kept low.
